Hi Bonnie,

How would you set, for example, font at a subclass level so that it is inherited by instances of the controls when I place them on a form. If I set font property for a subclass, compile it into a library, add the library to Toolbox, drag the class from Toolbox to a form, the piece of code that sets Font property for the subclass gets copied into form's code. If at a later time I deside to change font for the subclass, it will have no effect on instances of the subclass I already placed on forms. Am I missing something?

Thanks,

Yuriy

>That's it. These controls can't be sub-classed visually, but as you can see, it's easy enough to do it in code. I have all the basic controls sub-classed in one class library file. Once they're added to the ToolBox, then can be dragged onto any design surface in the IDE.

>To add to the ToolBox, do the following: When you have the IDE open in the designer view (not the code view), go to the ToolBox, right-click anywhere and choose the Add/Remove Items, click on Browse and find the .DLL where your sub-classed controls are (you obviously needed to have compiled the class library after you created it). That's it ... they'll then be added to your ToolBox.
